Lohmann Classic
Bikes

Inventor and designer Hermann Teegen (1899-1962)
is the spiritual father of Lohmann engines.
He designed several similar engines, 3 of which
were patented.

From one of these prototypes, over a period
of 3 years, the current 18cc Lohmann engine
was developed. It first appeared in 1950. 51,000
were built by August 1954.

Although in test reports of the time, it was specifically
pointed out that the engine was not a genuine
diesel, Lohmann advertising subsequently marketed
it as a ‘bicycle-diesel engine’ (ie
‘Fahrrad-Dielelmotor’ in advertising
leaflet below)

Description

1952 Lohmann 18cc on a York Bicycle

The 18cc 2-stroke Lohmann engine
was officially described as a ‘mixture
compressing self-igniting two-cycle
motor.’ When it originally
went on sale in Great Britain, the
price was just under £25 10/-

There’s neither carburettor
nor ignition system. Instead the
engine works on a variable compression
ignition system, which is moderated
by the twistgrips.
